`To all whom t muy concern.'

Be it known that l, Cnoin M. BiLLinos, a citizen oi the United States ot America., and a resident oi Brooklyn, county oit hing-s, and

'State of New York, have invented certain new and useiul improvements in Motor Parcel-Vehicles, of which the following is i a specii'ication, reference being had to the accompanying drawings7 forming a part thereof.

My present invention relates particularly to motor vehicles of the type employed for lig t delivery purposes. The objects of the invention are to provide a vehicle of this type which will be relatively light and inenpensive both in the matter ot' tirst cost and in the matter of updreep.` y

Special features of' the invention relate to the mounting andcooling ot the motor and to the construction ot the parcel compartment.

These ,and various other eatur invention will appear more fully speciiication proceeds, and will be stood Afrom a consideration of the es of the i as the underpanying drawings wherein l have disclosed -the invention vtypilied in a practical com mercial form.

ln the drawings referred to7 Figure l is a side elevation and part sectional view oit" the vehicle.

Fig. 2 is a top plan view of the same. The vehicle in the iorm disclosed is of 7V supporting a traine worlr 8 on which is mounted a parcel compartinentl or box 9, the latter preferably being detachable for purposes of loading and unloading, and being held detachably in place, Yfor instance, by the clamp bolts, 10.

At the rear end of the parcel compartment is a stationary dash 11, and inclined downwardly and rearwardly from this dash is the foot board l2. A t the rear and substantially over the drive wheel 5 is provided a suitable seat 13 for the operator.

The downwardly inclined foot board provides a compartment therebeneath, which is highest at the front and tapered in height toward the rear of the vehicle. Nithin this chamber is the motor which preferably is of the internal combustion type.

As disclosed herein, this motor is of the is mounted the crank shaft carrying the dy wheel 15. rhis motor is indicated as of the air cooled type and is shown mounted crosswise of the frame with the iiy wheel disposed at the forward sidethereoi inthe higher portion of the motor chamber. The fly wheel is shown formed with Jr'an blades 16 for inducing a cui-rent of air from the front and for forcingthe same rearwardly over and about the motor cylinders. The downwardly inclined surface of the foot board overlying the fly wheel and motor cylinders contines this current of air and causes the saine to flow downwardly and about the cylinders.

vThe low of the cooling current of air rearwardly beneath the vehicle to the motor is facilitated by providing a deflector beneath the forward portion of the vehicle, involving first a. downwardly inclined or curved portion 17 and an upwardly curved or inclined portion 18 extending from the lowest point of the downwardly and rearwardly inclined portion rearwardly towards the motor chamber. rlhe` arrows in Fig. 1

denote the flow of the current of air first downwardly and thence upwardly beneath wheel over and about the motor cylinders. l lind this arrangement provides very eifective cooling of the motor.

Another feature as regards the cooling of the motor is the location of the valve chambers 19-20 at the forward sides of the motor cylinders directly in rear of Vthe ily wheel, as indicated in Fig. l. lThis provides in effect for a streanrline flow of cooling air from the Vfly wheel about the motor cylinders, eilectually cooling the valvesand keeping the cylinders cooled to the properl degrec.

est the sides, the motor chamber is prei:- erably closed in by the walls 21 shows as arranged on lines converging .rearwardly towardthe central drive wheel. Thesesi'de walls are shown provided with Ventilating louvers 22 to permit free escape of the air and to prevent it pocketing within the rearward tapering motor chamber.

By means of the construction and arment is of special advantage, in that it per` mits the vehicle being made continuous use 'of the fan fly wheel referred to.

of, since eXtra compartments may be provided and kept loaded ready to be secured on the vehicle as soon as the empty compartment is removed therefrom.

The stream-lining of the air flow beneath the forward portion of the vehicle reduces wind resistance, eddies, etc., and provides for a smooth continuous flow of cooling air direct to the motor, and said flow as above pointed out, is continued by the fan fly wheel and stream line construction of the motor.

What I claim is:

l. A motor vehicle of the class described, provided with a rearwardly extending air deflector beneath the forward portion of the same, and an internal combustion engine of the opposed cylinder type, and arranged at the rearward portion of said air dellector with the cylinders disposed transversely of the vehicle, said engine having a flywheel at the forward side thereof, provided with fan blades for carrying the current of air from the deflector rearwardly, over the motor cylinders,"the said motor cylinders having valve pockets at the forward side thereof immediately in the rear of the flywheel to receive the full effect of the cooling flow from said flywheel, and to, in effect, stream-line the motor toward the rear.

2'. A motor vehicle of the class described provided with a downwardly and rearwardly inclined foot board and an internal combustion engine of the opposed cylinder type disposed beneath the foot board with the cylinders transversely of the vehicle and the fly wheel at the forward side thereof, said fly wheel being provided with fan blades for inducing a current of cooling airV from beneath the front of the vehicle rearwardly beneath the downwardly inclined foot board and about the cylinders, and the cylinders of said motor having valve pockets at the forward side thereof directly in rear 3. A motor vehicle of the class described provided with a downwardly and rearwardly inclined foot board and an internal combustion engine of the opposed cylinder type disposed beneath the foot board with the cylinders transversely of the vehicle and the fly wheel at the forward side thereof, said fly wheel being provided with fan blades for inducing a current of cooling air from beneath the front of the vehicle rearwardly beneath the downwardly inclinedV foot board and about the cylinders, and an air deflector beneath the forward portion of the vehicle in advanceof the fly wheel and provided with a downwardly and rearwardly inclined portion terminating in an upwardly inclined portion extending rearwardly toward the fan fly wheel.

el. A motor vehicle of the class described provided with a downwardly and rearwardly inclined foot board and an internal combustion engine of the opposed cylinder type disposed beneath the foot board with the cylinders transversely of the vehicle and the fly wheel at the forward side thereof, said fly wheel being provided with fan blades for inducing a current of cooling air from beneath the front of the vehicle rearwardly beneath the downwardly inclined foot board and about the cylinders, and an air deflector beneath the forward portion of the vehicle in advance of the fly wheel and provided with a downwardly andV rearwardly inclined portion Jterminating in an upwardly inclined portion extending rearwardly toward the fan ily wheel, said deflector serving to stream-line the air currents rearwardly to the motor, andthe motor cylinders having the valve enlargements at the forward side thereof to thereby stream-line the air currents rearwardlyover the motor cylinders.

5. A motorvehicle of the class described provided with a downwardly and rearwardly inclined foot board and an internal combustion engine of the opposed cylinder type disposed beneath the foot board with the cylinders transversely of the vehicle and the fly wheel at the forward side thereof, said fly wheel being provided with fan blades for inducing a current of cooling air from beneath the front of the vehicle rearwardly beneath the downwardly inclined foot board and about the cylinders, the motor compartment beneath the downwardly Vinclined foot board having rearwardly convergent side walls provided with ventilating louvers therein.

In witness whereof, I hereunto set my hand this 27th day of September, 1919.
